Multi-split air conditioning in Finchley
Twin and triple systems suit Finchley homes where bedrooms sit above the kitchen and one rear wall can take the outdoor unit. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
Multi-split is a good fit for Finchley flats and maisonettes where only a balcony or one rear wall is available. We cover Finchley as part of London, roughly 8 miles from central London. Homes in N3 are all within our coverage.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.

We book surveys in Finchley at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. Surveys in Finchley cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
